Clean, biodegradable structure for stem cell growth
Medical scientists were shocked to discover that virtually all human embryonic stem cell lines being used in 2005 were contaminated. Animal byproducts used to line Petri dishes had left traces on the human cells. If those cells had been implanted in a human body they likely would have been rejected by the patient's immune system.
Even today, with new stem cell lines approved for use in medical research, there remains a risk that these cells........Go to the Research news blog (Added on 2/3/2010 7:33:16 AM)
Curing More Cervical Cancer PatientsCervical cancer is highly curable when caught early. But in a third of cases, the tumor responds poorly to treatment or recurs later, when cure is much less likely.
Quicker identification of non-responding tumors appears to be possible using a new mathematical model developed by scientists at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Multiple sclerosis and the seasonPrior studies have shown multiple sclerosis (MS) patients are more often born in spring than in any other season, indicating that there is an environmental risk factor for the disease. A paper in the journal Neurology, evaluated for f1000 Medicine by Emmanuelle Waubant and Ellen Mowry, now suggests that this seasonal effect is mediated by the gene HLA-DRB1.
